Semiconductor integrated circuit device in which a conductive film is
formed over a trap film which in turn is formed over a titanium film

摘要：

The semiconductor device is formed according to the following steps. A TiN film 71 and a W film 72 are deposited on a silicon oxide film 64 including the inside of a via-hole 66 by the CVD method and thereafter, the W film 72 and TiN film 71 on the silicon oxide film 64 are etched back to leave only the inside of the via-hole 66 and form a plug 73. Then, a TiN film 74, Al-alloy film 75, and Ti film 76 are deposited on the silicon oxide film 64 including the surface of the plug 73 by the sputtering method and thereafter, the Ti film 76, Al-alloy film 75, and TiN film 74 are patterned to form second-layer wirings 77 and 78.

摘要（中）：

根据以下步骤形成半导体器件。通过CVD法将TiN膜71和W膜72沉积在包括通孔66内部的氧化硅膜64上，然后将氧化硅膜64上的W膜72和TiN膜71回蚀仅留下通孔66的内部并形成插头73.然后，将TiN膜74，Al合金膜75和Ti膜76沉积在包括插塞73的表面的氧化硅膜64上，通过溅射法，然后对Ti膜76，Al合金膜75和TiN膜74进行图案化以形成第二层布线77和78。
